When a publisher hasn’t announced when a season ends, GGS still shows a date, tagged EST., projected from that game’s own past seasons. That is a promise worth checking. So we went back through every version of our season database saved since November 2025, found each season where we showed an estimate rather than an official date, and compared it with the day the season actually ended.

The short answer: 18 estimated seasons have ended so far. We got 4 exactly right, 13 within a week, and missed 5 by more than a week, one of them by a month. The median miss was 6.5 days. And when we were wrong, we were usually wrong in the same direction: the season ended sooner than we projected.

How the estimate works

The rule is deliberately simple. We take the start date of the current season and add the median length of that game’s recent seasons. A median ignores one-off outliers (a season stretched for a holiday, a short “mini season”) better than an average does. The estimate only shows while there is no official date. The moment a publisher announces one, it replaces the estimate the same day, which is why most of these seasons show an estimate for a few weeks and then switch to a confirmed date.

Every estimate we showed, and what happened

“First shown” is the first day the estimate appeared on the game page. The estimate stayed the same until an official date replaced it.

What the numbers say

  • Fixed-cadence games are trivially predictable. Call of Duty: Mobile (35-day seasons), Genshin Impact (42-day versions), Rainbow Six Siege (91-day seasons) and Final Fantasy XIV hit the projected day exactly, in some cases more than 80 days out. For these games the EST. tag is conservative.
  • Misses skew early. Of the 14 seasons we didn’t nail, 11 ended sooner than projected and only 3 later. Publishers shorten seasons more often than they stretch them, typically to line up with a big launch: Battlefield 6’s Season 3 ended 27 days before its cadence suggested, and Warframe’s Nora’s Mix: Time Tempests closed 31 days early. Practical advice: if a battle pass matters to you, plan against the estimate minus a week, not the estimate itself.
  • Most misses came from games with irregular calendars. Battlefield 6, Warframe and World of Warcraft change season length with their content plans (see which games keep their schedules). For those, the estimate is a rough guide.

What about dates we marked as confirmed?

Estimates are the easy target. The harder test is our confirmed dates, the ones shown without an EST. tag. Over the same period, 48 seasons across 33 games had a date marked confirmed on GGS before they ended. 42 of them (88%) ended on that day, give or take one day (the one-day slack covers time-zone differences between a publisher’s local announcement and UTC). Six did not:

We are publishing these because they are ours. In some cases the publisher moved the date after announcing it (Teamfight Tactics’ Set 17 ran four weeks past the date first given); in others we recorded the date wrong or too early. Either way, a “confirmed” label that is wrong one time in eight is not good enough. The tracker now re-checks every game against official sources daily, and every correction is kept on the game page with the date it replaced, as the editorial policy describes.

How we measured this

  • Source: every daily version of the GGS season database from November 15, 2025 to September 25, 2026 (197 daily snapshots). This site’s data is version-controlled, so the history is complete and can’t be edited after the fact.
  • Estimates: for each day, we recalculated the estimate exactly as the site does today (start date plus median of recent season lengths) for every live game without an official end date, then matched it to the season’s actual end in our season history.
  • Confirmed dates: we took the first date marked confirmed while the season was still running and compared it with the actual end. Dates added after a season had already ended were excluded.
  • Limits: 18 estimated seasons is a small sample, and it will grow. We will update this page as more seasons close.
